Abstract

fetched live from OpenAlex

Screening tests for aflatoxins B1, B2, G1 and G2, ochratoxin A and sterigmatocystin productionwere performed in 13 strains of Aspergillus spp, isolated from the terrestrial environment in the BrazilianAtlantic Rainforest (São Paulo State/Brazil). Coconut agar medium and moistened corn were employed assubstrates. The fungal extracts obtained from both media were submitted to thin-layer chromatography and the toxins were estimated according to the intensity of their fluorescence observed under UV light. None of the tested strains presented any of the mentioned mycotoxins. Because many unknown fluorescent spots were present, it was necessary to proceed a confirmation step using multiple chromatography, two dimensional chromatography and derivatization. In view of the accuracy of the employed methods and thepresence of many unknown fluorescent spots, the need of further studies on the production of others mycotoxins of fungi isolated under tropical conditions is justified.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
